' or fuel by temporarily closing the air inlet i .lle it known that l, GAnumT FW. HEN- lucns, ot llidianapolis, county of Marion,

and State ot lndiana. have 4invented e certain new and useful Carhureternand l do hereby declare that the following is a full, clear. and cxactdeecription thereof, referf ings. in which lilre numerals reiter to like parte.

The object of this invention isto provide an improved` construction di" carburetere wherein the suction oit' the piston ofthe en- ,gine may loe utilized in emergency for priming the cylinder-'of the engine witli gasolene while starting the engine7 especially ,during cold Weather. il feature of the invention consiste in combining with the means fo'r temporarily l closing the oir inlet', means for stopping or limiting the opening and closing movements ot the emergency valve in the air lnlet.

The full nature of this invention will be understood from the accompanying drawings and the following description and claims. i

In the drawings Figurel is e central vertical section through the carburetor supplied with my improvement, showing the parte in normal operative position and the air valve I in then'ormel position during use oi' the lli titl

T ere appears in the drawings a float chamber .10 with a, float 11 therein having gesolene supply pipe 12, a Valve 13 for controlling the admission of gasoiene into the float chamber and which. vulve is controlled by the doet 11. i A

lll is the Weste outlet und l5 is the fuel inlet end ol2 the mixing chamber 16, 'which fuel inletis controlled by the needle Valve 17.

Whom however.. the engine is being Started and especially in cold `weather. the cilnider'o't the engine can be tion Shown in Fig. 2, thus cutting oli the supply of air and causing the engine pra`ctically 'o suck up or pump up fuel through chamber lo and outlet 18 to the cylinder, whereupon thc valve is immediately releasedfuel in the carburcter.

side of the air tube 2?. is provided for 'stopping the closingmovcnient of the valve. ll-hen'thc part .27 is released the Springitl i immediately opone the valve to its normal position. lt is thus eeen that ut the time ot' cranking'v the engine. the cylinder can he v conveniently and easily primed instantly.

- By the word "t emergency need herein in conncctioi'l with the valve '2l is meant a valve to he used iu the'caee of emergencies when thc rcmailiing' vzilvclaud'inechanism is. insufficient to malte the carburetor work. This valve Q-l is not neoeseury for starting` hthe engine ordinarily and exceptin warm' occasion; ol' very7 sudden changes in the AWheetlner or when the fue] inlet is partially or vtotally clogged by Sonie temporary obstruction, Wliether it be due to the weather or some other unse, an eniergency then existe which `is niet and overcome by; the emergency valve 2l, 'orby closing inthe fuel may be drawn through the fuel lnlet i or condition ot' the Weather, or 'il there be my invention in concerned. l provide in the t n l m Ea crank shaft 25 extending diainetrically;v cncebeing had to the vaccompanying draw primed by closing the valve Q4 to the posi-4 for the immediate admixturc of air with t-lie" A stop 30, here 1n f the ,term ot' a pin extending through the weather and when the carburetor is in goed condition, but; 1x1-cold weather and on thev and the engine started regerdlcssof the cold ing by the valve Q1 and loelow it, thabio Bil i?? extend to any convenient place for clontill eoA
